jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is light weight (around 19KB when Minified & Gzipped), cross-browser (IE 6.0+, FF 2+, Safari 3.0+, Opera 9.0+, Chrome), and supports CSS1-3 selectors.
jQuery allows you to write Unobtrusive JavaScript by separating the “behavior” characteristics from the HTML structure. For example, instead of directly specifying the on-click event handler in the specification of a button element, a jQuery driven page would first identify the button element, and then modify its on-click event handler.
Features:
- DOM element selections
- DOM traversal and modification, (including support for CSS 1-3 and basic XPath)
- Events
- CSS manipulation
- Effects and animations
- Ajax
- Extensibility
- Utilities – such as browser version and the each function.
- JavaScript Plugins
